The CORE+ SS Top is a thick, extra warm short sleeve base layer for cold conditions. The thermal properties retain the bodies core heat at the highest level in icy conditions and allow sweat to be wicked away quickly from the skin at a rapid rate. The compression weave is designed to cling tight to the body to help with muscle fatigue and rapid wicking. The body-mapped design has been athletically shaped, so the high wicking fabric can sit tight to the body in order to absorb and disperse as much sweat as possible, all the while allowing maximum movement in the high stretch areas. The warm nature and fast sweat distribution properties mean that the Core+ is a perfect base layer under warm outers in cold climates as well as a standalone layer in the mild parts of the day. The CORE+ should be used in temperatures ranging from -5C to 10C for maximum performance. For warmer conditions, the CORE range is recommended.
